  1. Wireless Security Presented by Colby Carlisle

  2. Wireless Networking Defined • A type of local-area network that uses high-frequency radio waves rather than wires to communicate between nodes.

  3. Issues • No need for physical access • Easy and convenient to use • Confidentiality and Integrity concerns for users • Technologies commonly used to secure networks are vulnerable to attacks

  4. The Tradeoff • Linksys Routers • Zero Configuration

  5. Be careful whom you associate with... • Malicious Associations • Exploits how users connect to AP’s • Can create backdoors into other networks • Man-in-the-Middle • Hotspotter

  6. What can you do? • Use encryption • WEP • WPA • WPA2

  7. WEP • Wired Equivalent Privacy • Still widely used • Encryption algorithm flawed • Vulnerability widely known • Kismet

  8. WPA • WiFi Protected Access • Intermediary step between WEP and WPA2 • Temporal Key Integrity Protocol • Personal vs. Enterprise

  9. WPA2 • Implements mandatory elements of the 802.11i standard • Advanced Encryption Standard

  10. Steps to securing your network • Use the best encryption possible • Change your router’s default configuration • Disable the SSID broadcast option • Disable DHCP • Enable MAC address filtering if possible
